LIQUID DISPENSER.

Application filed February 15, 1924. Serial No. 693,006.

To all whom. it may concern:

Be it known that I. Josnrrr N. BUnNo, a citizen of the United States, and a resident oi Chicago, county of (look, State of Illi- 5 nois, have invented certain new and useful Improvements in Liquid Dispensers, of which the following isa specification.

This invention relates to liquid dispensers. "An important object of the invention to provide in a device of the character mentioned an improvedmeans whereby the flow of liquid from one sonrco oi supply may be established or discontinued irrespective of and independently of another source as desired. i v

Another object of the invention is to provide in a device of the character inentioimd a means whereby the flow of liquid from the independent sources may be: established si multaneously tov ell'ectan equal or substan tially equal flow of liquids."

A further object olthe invention is to siu'qjlity generally the construction of the sevcrat elements entering into the conihiniu tion and provide a device of the character mentioned which is reliable in operation and capable of withstanding; the severe use. in-' cident to varying conditions under which theapparatus may he required to operate.

Uther objects and certain advantages of the invention will become apparenttroni the following description when taken in connection with the accompanying drawings in which Figure l'is side elevation of the device (inli odying my invention.

oi illustrutionis shown what i atpi'esmit consider the preferred formot' my 111mm in the drawings, wherein :For the .PLH'POSQ with a flange and internally screw-threaded pipe coupling 8 adapted to connect the device .to a suitable source of liquid supply. notshown. The passaz 'e as will be noted particularly from Figure 7, terminates in a chamber 9 communicating with an escape opening 10 through which a liquidsuch as coffee, for example, is adapted to escape under conditions hereinafter-more particularly described. The casting, 5is also provided with a vertical passage 1lcon1munieating with an escapeopeninr12 through which a liquid such as milk is adaptedto escape under conditions hereinafter more particularly pointed out. The upperei'id 0t it the passage 11 is screw-threaded as shown at 13 and is adapted for the reception otthe screw-threaded end of a depending nipple l l'connectedto and connnunica'ting with a liquid container receptacle 15 into whichlisiadapted to be placed a liquid container such as a bottle 16 adapted for the reception of a liquid such for example as milk. It will be appreciated that while I have shown the source or milk supply in the form of a bottle 16 this bottle. may be dispensed with as well as the liquid container receptacle 15, in which case the passage 11 may be connected directly as by means of a pipe, not shown, to a suitable the reception of milk.

The flow of liquid from the passages 7 and 11 is controlled through the'instrumentality of valves 17 and. 18, respectively. These valves respectively comprise wings 19 and 20, carrying extensions 21 and 22 having openings 23 and 24- formed therein, which openings are provided with vents 25 and 26 adapted, upon movement of the wings 19 and 20. to establish communication between the passages 7 and 11 and the openings ..3 and 24;. respectively. The wings 19 and 20 are pivotally connected. to or loosely n'iounie, ed upon shafts 27 and 28, respectively, which are journaled to the casting 5 and adapted to rotate with respect thereto. To these shafts are rigidly connected valve op crating; arn'is29 and 30, confined between lugs 31. and the extensions 21 and 22. carried by the wings 19 and 20 so that when the arms 29 and 30 are moved through the instrumentality of the shafts 27 a11d'28 the. wings 19 and 20 are correspondingly actuated. While the wings 1.9 and 20 are so locked to the shafts 27 and 28 as to rotate therewith. they are nevertheless free to slightly move longitudinally thereupon in order to permit an intimate engagement of the wings 19 and 20 with the faces of the casting 5 within which the exit openings and 12 are formed. This intimate engagement of the wings 19 and 20 with the face of the casting 51's effected through the instrumentality of thrust springs 32 and disposed intermediate the arms 29 and 30 and the wings 19 and 20, respectively. The thrust springs 30 and 3.1. are slightly bowed, as shown most clearly in Figure 1, and are retained'in position upon the Wings 19 and 20 byreason of the fact that their outer ends are confined. within notches 3 1 and formed in the wings 19' and 20, whereas their opposite ends are maintained in engagement with lugs 36 and 37 carried at the free ends of the wings 19 and 20 respectively;

To the. shafts 27 and 28 are connectedhub members 38 and 39 with which are integrallyformed lugs or arms il-0 and 1-1 carrying pins 42 and 4t3 against which rest corresponding ends of torsional springs 14: and 15 coiled around the shafts 27 and 28, and held thereon by means of collars 3S and 39. These springs terminate in relatively long arms adapted to engage the stem 6 on the under sidethereof and when assembled are maintained under more or lesstension which is utilized to, normally maintain the valves 17: and 18 in their. respective positions shown in: Figure 2, in which positions the exit o enings 10 and 12 leading from the passages T- and 11, respectively, are closed. In order to: limit the. movement of the valves 17 and-18 in one direction the shafts 27 and are provided withyfingers 16 and 17 adapted to engage the stem. 6, as shown most clearly in Figurewl.

Tothe under side of the casting 5 there isconnected a pair of lugs 4-8 within which is journaledatransversely disposed shaft -10 upon which is mounted amovable actuating plate 50having cars 51. formed integral therewith through which the transversely disposed-shaft -19 extends. ()ne of these-ears, as shown in, Figure 7. is provided with a stop 52 which is adapted to engagethe casth1g5 to limit the movement in one direction ofthe rocker member 50, as will hereinafter moreclearly appear. This same car is providedwith acam face 53 adapted to engage and cooperate with-the arm 4-1 to move the same and thereby effect an opening. of the valveli. Tothe rocker member 50 there is pivotally connectedalatch lever 5 1, the pivotal connection between the latch lever and rocker member: being, indicated by the nu merali This latch lever is provided at its opposite. end .vith aadepcnding roller 56 adapted to ride over the slightly curved face of a lift finger 57 carried by the rocker member 50. The latch lever is provided with a depending trip arm 58 carrying at its lower end a trip finger 59 disposed at right angles thereto. At that end of the latch lever 541 to which the roller 56 is connected there is carried an upstanding pin or lug 60 adapted to engage and cooperate with the arm to effect suchmovement of the shaft 28 as will cause the valve 18 to be opened against the influence of the spring in a manner hereinafter more particularly described. The latch lever 54- is maintained normally in its position shown in Figures 3 and 5 through the instrumentality of. a spring 61 coiled about the pivot and having one end maintained within a notch 62 formed in the ear 51, the other end of this spring being suitably connected to the latch lever 5d as shown at. 63. By arranging the spring 61 as described and connecting the same to the flange 51 and'the latch lever 54: it will be appreciated that this single tension means may be utilized to maintain the latch lever 54; and the oscillating member 50 in their respective positions most clearly understood from an inspection of Figures 3 to 7, inclusive. It willibe noted that when these elements are normally positioned the free endof. thelatch lever 5-1 is located directly over the finger 5? which position is necessary in order to permit simultaneous opening of the valves 17 and 18 when it is desired to dispense the liquid simultaneously from the passages 7 and 11.

To the hub member 38 thereis connected a handle (34 which is adapted to be operated manually when. it is desired to rotate the shaft 28 and open the valve 18 independent ly of the valve 17, thereby permitting the liquid to escape from the passage 11 only, whic. passage as hereinbefore explained is adapted to comnnmicate with a source of milk supply.

The entire. structure herein shown and described is adapted to be suitably supporter upon a base or other supporting structure, not shown and is also adapted to be provided with a. housingor cover, not shown. enclosing. the several operative elements of the apparatus to prevent the same against injury and protect them from dirt or other undesirable foreign matter which might otherwise. collect thereon.

The ap 'iaratus embodying my invention although not restricted to such use is particularly adapted to be used in restaurants and operated by a countcrman for dispensing either milk, coffee or a mixture of the two liquids. When it is desired to dispense only coffee. cup or other suitable container is introduced intermediate the arcuate shaped arms 65 carried by the depending lever 6 connected to the roclzer member 50 and at the same time ln'ought into engagey me ment with the trip finger 59. Upon further introduction of thecup or other receptacle the trip arm 58 is moved in the direction of the arrow A shown in Figure 1 where upon the latch lever 54 is moved about its pivot against the influence of the spring 61 causing the free end of the latch memher to disengage from the finger 57 and so position itself with respect thereto as to permit the finger 57 to move in an unobstructed manner. After the free end of the latch lever 54 has been moved a sufficient distance to permit the finger 57 to clear the same the cup or other receptacle i further. introduced causing the lever 66 to move in the direction of the arrow B shown in Figure 1. This movement of the lever 66 causes the rocker member 50 to move about the axis of the shaft 49 as a pivot whereupon the cam face 53 of the flange 51 lifts the arm 41 thereby rotating the shaft 27 and effecting a lifting or open- U of the valve 17 to permit the egress of liquid from the passage 7 through the exit opening 10. The valve 18 under such conditions is permitted to remain closed for r the reason that the free endof the latch lever 54 having been moved as above described from its POSltlOll directly over the finger 57permits this finger to move in an unobstructedmanner. r j

In the event it is desired to dispense. only milk for example, from the passage 11 a lever 64 connected to the hubmember 38 is depressed against the tension of the spring 45 whereupon the shaft 28 is rotated and the .valve 18 islifted thereby opening the exit opening 12. Itwill'he appreciated that after a quantity of coffee has been dispensed the lever 64 may be, depressed to release a desired quantity of milk so that the resultant content of the cup or receptacle previously introduced may be that of a de sired quantity of coffee into which hasbeen introduced a desired proportion of milk, such proportions of course being governed or determined by the length of time each of these. liquids has been dispensed inclependentlyhof each other.

Should it be desired tOl operate the two valves 17 and 18simultaneously in order to dispense equal amounts of liquid from their respective sources of supply, the cup or other receptacle is introduced between the arcuate shaped arms without dlsturblng the positum of the dependmg trip arm 58 and the leverlSG, upon further introduction of the cup, is moved a sufficient distance in the direction of the arrow B shown in Fig ure 1 to appreciably move the rocker me1nber 50 about the shaft 49 as an axis. With the latch lever 54 positioned as shown most clearly in Figures 3 to 55, inclusive, the free end of thesame is lifted as the rocker mem ber 50 is moved and by reason of the enliquid from said gagement between the free end of the latch lever 54 and the arm 40 the shaft 28 is rotated thus effecting operation of the valve 18 and opening of the exit opening 12. At the same time the valve 18 is opened the valve 17 is simultaneously opened in the manner hereinbefore described. Upon withdrawing the cupor other receptacle from engagement witlr the lever 66 the valves 17 and 18 are moved to their normal positions, shown in Figure 2, through the instrumentality of. the springs 44 and 45 and the lever 66 is moved to its normal position shown most clearly in Figure 1.

While I have shown and described what I at present consider the preferred form of my invention it is to be understood that various changes in the size, shape, arrangement and proportion of elements may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
